You could use a resistor (with proper power rating, which you probably know) in series as the field coil in 91 is not used as a filter.
What I do not understand there, if they use 2 speakers (I guess 2nd is an option) they plug the second field coil between the B+ and Chassis which (if the fields are similar) would create a nice divider and lower B+ quite a bit. Or is the second one some sort of a twitter and has a field of very high resistance?
